Why does BRS recommend this?

BRS Reef Saver Live Rock is one of the most unique rocks that is available on the market today.  Reef Saver is not taken directly from the ocean, and does not impact living coral reef structures in any form.  It is always 100% free of nuisance algae or any type of pests.  

BRS Reef Saver rock is one of the easiest rocks to work with when aquascaping new tanks or adding more rock to an established tank.

BRS recommends curing all rock before being used in an established system.

Product Questions

Hi there,
What is the recommended amount of rock per gallon? I'm aquascaping a JBJ 28 LED tank. thanks!
Question by: Chris on Sep 30, 2013 8:07:00 AM
Hey Chris,
We recommend a pound per gallon as a good ballpark place to start. It will give a nice middle of the road aqua-scape and is what most folks are looking for!
Answer by: Bulk Reef Supply on Sep 30, 2013 8:07:00 AM
I'm setting up a 35 gallon 20inX20in cube, out of the three pukani, reef saver or Fiji which offers the smaller pieces my tank requires for me to get the best results aquascaping? Thanks!
Question by: Kyle on Nov 22, 2013 8:48:00 PM
Hi Kyle,
Fiji and Reef Saver offer the smallest size pieces. Personally I prefer reefsaver in these types of situations as it is really easy to stack and create your aquascape.
Answer by: Bulk Reef Supply on Nov 22, 2013 8:48:00 PM
Is the price shown here the price per pound? Thanks.
Question by: Steve on Sep 5, 2013 6:11:00 PM
Hi Steve,
Yes the rock is sold by the pound, so the quantity you enter in the quantity field is the number of pounds you are ordering.
Answer by: Bulk Reef Supply on Sep 5, 2013 6:11:00 PM
Hi, I am looking into getting into a reef tank. I understand I need to cure the rock, but could I keep fish during the process? Also, would 60 pounds of reef saver be a good amount for a 40 breeder?
Question by: Ethan Wood on Apr 10, 2016 4:52:00 AM
Great question!
You will not be able to keep fish with curing rock as the nutrient levels will fluctuate too much. Around 40 lbs would be recommended for weight. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Apr 13, 2016 6:57:00 PM
Do the rock come in certain sizes or just random?
Question by: Bobby on Feb 9, 2014 6:38:00 PM
Hi Bobby,
There made by nature so they are like snowflakes, each piece is entirely different, though most range in the softball to football size.
Answer by: Bulk Reef Supply on Feb 9, 2014 6:38:00 PM
What is the weight of one rock?
Question by: Logan on Apr 25, 2016 11:42:00 AM
Great question!
It will range by size of the pieces however on average a football sized piece will be 5 lbs.
Answer by: Connor (Admin) on Apr 27, 2016 2:44:00 PM
I've just read a couple of articles saying that this rock has phosphates in it and to give it a Muriatic acid bath followed a Lanthanum Chloride treatment, is all this really necessary?
Question by: Vinny on Mar 30, 2016 7:22:00 AM
Great question!
You will not need any acid or other treatment for the rock. By curing the rock in heated saltwater for 6-8 weeks you can remove all dead and decaying elements (Phosphate is not "In" the rock rather it is part of the dead and decaying elements) Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Mar 31, 2016 7:06:00 PM
I am setting up a new tank and will add the rock with live sand and water at the same time. Can I just put this rock directly from the box into the tank without curing in water for a couple of weeks? Thanks,
Question by: Jonathon C on Mar 17, 2016 1:09:00 PM
Great question!
You certainly can cure the rock in the tank without much issue. You will want the rock to sit in the tank with no lights and high flow for 4-8 weeks. After which you can perform massive water changes of 100% and ensure the nitrogen cycle has begun. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Mar 18, 2016 9:53:00 AM
Is the price for the rock for a piece or by pound? If so, how big is the piece?
Question by: Frank on Apr 12, 2016 5:38:00 PM
Great question!
All rock is sold by the pound. On average a football sized piece will weigh between 5-10 lbs. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Apr 18, 2016 6:19:00 PM
Do you ship reef saver rocks to Canada? Your website says no tonga, pukari etc.
Question by: Leo on Apr 20, 2014 11:26:00 AM
Hi Leo,
Yes the reef saver rock can be shipped to Canada.
Answer by: Bulk Reef Supply on Apr 20, 2014 11:26:00 AM
Hey guys! I ordered a bit over 30# reef saver for a new tank.
Would it be recommended to toss in a bit of live rock from a local pet store all into the container I'm going to be curing these in?
If yes - is only a heater and a couple powerheads sufficient for equipment, or do I need to introduce a filter now if wet live rock is included?
And lastly - would it make a difference if I include 1lb of live rock vs 5lb? Or only the rate at which the reef saver will become populated?

Question by: Zil on Dec 28, 2016 3:15:00 AM
Great question! You are all over it! Adding a cured/live rock to your curing bucket will act as a seed to bacterial colonies. All you need is circulation and heat to continue and finish the process. :-)
Answer by: Randy (Admin) on Jan 2, 2017 7:52:00 AM
I am starting a new tank with the Reef Saver Dry Live Rock and Caribsea Arag-Alive Fiji pink sand. Should I start the cycle with the sand first while I cure the rock and add the rock later? Or can I start the cycle with both the sand and rock? What is your recommendation?
Question by: Calvin on Apr 23, 2014 3:37:00 AM
Hi Calvin,
If your going to cycle the rock in the tank, I would just do your aquascape, add the sand, add the water, and then let the whole system cycle together.
Answer by: Bulk Reef Supply on Apr 23, 2014 3:37:00 AM
I'm just about ready to put the BRS Reef Saver I bought into my 46gal tank and start the cure and cycle. I'm planning to add a 20lb bag of live sand and a bottle of Bio-Spira as well to give the bacterial growth a jump start. My question is whether I need to add an external source of Ammonium for the cycle on a regular basis? It seems like the bacteria will need something to "eat". (It doesn't seem like BRS Reef Saver, live sand, or Bio-Spira will introduce any sources of nutrients for the bacteria to consume, or will they?)
Question by: Eric Bjorklund on Jan 25, 2017 9:16:00 AM
Hey there! It sounds like you are off to a good start with that game plan! A small bit of fish food would be more than enough to start the cycle and get your tank going. :-)
Answer by: Randy (Admin) on Jan 28, 2017 10:29:00 AM
I have a 75 gallon reef tank with only 60 pounds of live rock I want to buy 50 pounds of reef save dry rock but what is the process to do to add it to my existing tank without a problem
Question by: Christian on Aug 2, 2014 1:59:00 AM
Hi Christian,
The Reef Saver Rock is the cleanest of the rock so you don't have to worry about a cycle when adding it to an existing tank. You will get the best results by giving the rock a bit of a cure before adding it to the tank though. The simplest thing to do is to grab a container large enough to submerge the rock. Fill it up with your rock and some saltwater, throw a heater in it and let it sit for 4-6 weeks.
Answer by: Bulk Reef Supply on Aug 2, 2014 1:59:00 AM
I just received 100 pounds of your Reef saver rock, I am starting a new 180 gallon tank. Was wondering if I can add the rock then add the water and salt and let it cycle from 4 to 6 weeks and then add my fish? after my water has cycled do I need to do a water change how much of a water change do I need to do?also would 100 pounds of rock be sufficient for my 180 gallon tank?
Question by: George millette on Jan 25, 2017 5:01:00 PM
Hey there! It sounds like you have a pretty solid plan of attack and I would recommend the same! 100lbs would give you a nice minimalist aquascape, but if you plan to have a heavy bioload of fish you may need to add more rock or ceramic media. This will allow for more beneficial bacteria to live on the extra surface area. :-)
Answer by: Admin (Admin) on Jan 28, 2017 11:18:00 AM
Because this rock is considered to be devoid of all pests and algae is it still a requirement to cure it prior to beginning to cycling my tank or can I just aqua scape add sand, water and continue on ?
Question by: Chris on Mar 9, 2016 9:41:00 AM
Great question!
You will want to cure the rock still to build up a safe amount of bacteria and remove any dirt and contaminants as it is still removed out of the ground, Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Mar 9, 2016 3:54:00 PM
I am setting up a 120 gal and would like to buy 120lb of reef saver rock. Now if I use the Red Sea reef mature kit or Dr. Tim's bacteria to cycle the tank do I still need to do the 100% water change?
Question by: Michael Eaddy on Apr 3, 2016 10:09:00 PM
Great question!
We recommend curing the rock in a separate container to remove any excess nutrients before placing into the tank and starting the tanks cycle. If you prefer to cure in the tank we recommend curing for the same period and starting the cycle with the mature pro later. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Apr 6, 2016 6:50:00 PM
Hello, i was going to buy some of this rock but i see that it does not display by how many pounds you guys sell it. How many pounds is the rock displayed?
Question by: Max on Jun 13, 2015 5:17:00 PM
Great Question,
We sell all of our rock by the pound. We ask that you give us an estimate of how many lbs of rock you are looking for (Ex. 1 lb per Gallon) The pieces shown in the product photo are not actual pictures of the rock you will receive, more of an idea of shapes and sizes, the typical Reef saver will range between 5-15 lbs for a football sized piece.
Answer by: Connor (Admin) on Jun 15, 2015 4:17:00 PM
How big is each piece?
Question by: Chad on Mar 17, 2014 4:13:00 PM
Hey Chad,
Each piece is different which is why its sold by the lb. Pretty typical for most pieces to be in softball to football size range with a football size piece weight somewhere in the ball park of 7-8lbs.
Answer by: Bulk Reef Supply on Mar 17, 2014 4:13:00 PM
Hi I'm setting a 20 gal tank. Please recommend the quantity adequate. Can this be shipped to India??
Question by: Conrad on Feb 26, 2016 9:31:00 AM
Great question!
We typically recommend 1 pound per gallon around 20 pounds total. Unfortunately we do not offer international shipping outside of the US and Canada. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Feb 26, 2016 9:39:00 AM
I'm buying the dry live reef saver rock and I don't have the money to buy it all at once. Is it safe for fish or inverts to buy this rock in increments cure them in a separate container or trash can for a month like the video shows then when there done add them to the tank? Just double checking thank you
Question by: Scott Watson on Feb 12, 2017 12:47:00 AM
Hey there, great question! Adding small increments of the Reef Saver rock to an already established aquarium will not negatively affect the tank. The existing rock in the tank will help speed the colonization of the new rock with very minor spikes in ammonia or nitrate. :-)
Answer by: Admin (Admin) on Feb 13, 2017 2:25:00 PM
Where does this come from and what's its make up?
Question by: Donald Bowling on Apr 11, 2017 6:15:00 PM
Hey there,
The great thing about Reef Saver rock is that it is real reef rock. The advantage is that it comes from a land-based dead coral reef that is quarried in the US, so there is no impact to the ocean reef rock, and it's also significantly lower in residual organic material.

Have a great day!
Answer by: Zack (Admin) on Apr 23, 2017 8:23:00 PM
Just bought some of the reef saver rock. What temp should water be to cure. I'm going to be adding these to established reef with existing live rock. I'm going to cure for 3-4 weeks. Should I ever change the curing water while curing? When cure is done, do I just rinse rock off and add to tank or something else?
Question by: stanton on May 13, 2014 11:55:00 AM
Hey Stanton,
I would use water that is the same temperature as you will have the tank at. Pretty good bet that will be somewhere around 78 degrees or so. You don't need to do a water change while curing the rock but you want to get rid of all of that water when your done. If your curing in a separate container you can just move the rock to the tank. If your curing in the tank then do a 100% water change.
Answer by: Bulk Reef Supply on May 13, 2014 11:55:00 AM
Do we type how many pounds we need of the live rock in the quantity feild? Like I would need 20 so I would just Type 20 in the quantity feild and I would get 20 pounds??
Question by: Ben on May 16, 2016 9:00:00 PM
Great question! All of our Dry Live rock is sold by the pound, meaning, quantity entered stands for pounds (lbs). Ex: 20qty = 20lbs :)
Answer by: Carter (Admin) on May 24, 2016 11:24:00 AM
Hello I have the reef saver rock and wanted to know how many pounds to put in 60 gallon tank ?
Question by: Hector on Jun 7, 2014 9:41:00 AM
Hi Hector,
About 60lbs total should be great for a tank that size.
Answer by: Bulk Reef Supply on Jun 7, 2014 9:41:00 AM
Good Morning! I'm wanting to create a couple of islands in my reef tank hopefully creating a "bonsai" look. I've ordered 60 lbs of the reef saver rock and wanted a few of the shelves with the base. But it would only let me order a minimum of 20 lbs which came to almost a $100. Is there any way that I can order less than that? I'm not sure how much 20 lbs of the shelf rock would be and I only wanted a few pieces to add to each island. Thank you for your help~
Question by: Janet on Jan 22, 2014 4:31:00 AM
Hi Janet,
The 20lb minimum isn't because we don't want to let you buy less then 20lbs, its because a single rock weighs atleast 20lbs :-) Rocks with base are typically quiet large so if your looking for smaller/lighter pieces, the pieces without a base will be what your looking for :-)
Answer by: Bulk Reef Supply on Jan 22, 2014 4:31:00 AM
If this is 100% pest free, why does it need to be cured? I am replacing live rock I bought from a LFS in September of 2015 that I have been battling aptasia, bubble algae, and bryopsis with.
Question by: Randy on Jun 23, 2016 9:35:00 PM
Great question! We recommend curing all dry rock in order to establish a good starting population of beneficial bacteria within the pores. :-)
Answer by: Randy (Admin) on Jun 29, 2016 5:35:00 PM
I'm looking to add some dry rock to my existing setup? I will not be removing any of my current live rock I would just be adding the dry rock. So can I just put it right in or is there something I need to do to it first? Thanks for the help........Chris Turo
Question by: Chris T on Mar 31, 2014 1:28:00 PM
Hi Chris,
We would always recommend cycling any rock outside of an existing aquarium before adding to a tank with livestock, though as far as rock goes the Reef Saver rock is by far the cleanest rock out of the box.
Answer by: Bulk Reef Supply on Mar 31, 2014 1:28:00 PM
How much does the average reef saver rock weigh?
Question by: Travis on Nov 13, 2016 7:52:00 PM
No answers yet. Be the first to answer the question!
Whats the average weight per a rock?
Question by: peter on Apr 8, 2016 10:19:00 PM
Great question!
Depending on the size they can typically range from 5 - 10 lbs per piece. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Apr 12, 2016 5:32:00 PM
do you need to cure reef saver rock the same as you would live rock or is it fairly free of organics?
Question by: john on Sep 1, 2013 3:53:00 AM
Hey John,
We would advise cycling any type rock from any source because it just isn't worth the risk of your live stock not too. As far as the rock goes though, the reef saver is by far the cleanest of any of the rocks right off the bat.
Answer by: Bulk Reef Supply on Sep 1, 2013 3:53:00 AM
Howdy y'all, I've seen the video of Ryan chiseling and cutting the Pukani rock. Is the Reef Saver rock as easy to manipulate and cut? Thank you!
Question by: Blake on Oct 4, 2013 11:06:00 AM
Hi Blake,
The Reef Saver rock is much harder and not nearly as easy to manipulate. If you want to chisel out caves and the like I would highly recommend going with the pukani :-)
Answer by: Bulk Reef Supply on Oct 4, 2013 11:06:00 AM
I am in the process of planning a new tank, a JBJ 45 rimless Cube AIO and was wonder what is the recommended amount of rock for a tank this size as well as the correct amount of sand for it. the actual display portion of the tank will be 26 x 16 x 21 I was going to use the ocean direct original grade sand approximately 1- 2 inches deep. Would you recommend another type of rock for this?

Thank you.
Question by: Rob on Dec 23, 2013 1:28:00 AM
Hey Rob,
Great questions. For a tank your size 45-50lbs of rock should be right in the ballpark of what your looking for. Sand wise with the dimensions of your tank, coincidentally your also looking at 45lbs to get you about a 2" sand bed (half as much for a 1" sand bed). With most sands being sold in 20lb or 40lb bags, I would pick up a 40lb bag (or 2x 20lb bags) and you should be in great shape.
Answer by: Bulk Reef Supply on Dec 23, 2013 1:28:00 AM
does this rock have to acclamate
Question by: lynda on Oct 24, 2013 10:26:00 AM
Hi Lynda,
The rock isn't alive so it itself doesn't need to be acclimated. We would however recommend cycling any rock from any source being atleast cycled before adding to an existing aquarium to make sure there isn't any risk to your existing livestock.

Full Details

BRS Reef Saver Dry Aquarium Live Rock can be shipped to Canada.


BRS Reef Saver Dry Aquarium Live Rock, our environmentally friendly rock, works great for aquascaping. This rock is 100% free of nuisance algae and pests which can cause complete tank shut downs and is guaranteed to be free of apitasia, bubble algae, parasitic isopods, mantis shrimp, acro eating flat worms, little red bugs, fire worms, predatory nudibranchs, pyramidellid snails and other common pests. BRS Reef Saver rock comes in unique shapes that fit well together to make interesting and unique structures. BRS Reef Saver Rock arrives at our warehouse pre-soaked and rinsed. This is by far our cleanest rock.


How much rock do I need?

Knowing exactly how much Dry Live Rock you will need can be one of the hardest questions to answer since every tank and rock will be slightly different. A general guideline for Reef Saver Dry Live Rock, we suggest 3/4 to 1 pound of rock per gallon of display tank volume and may vary depending on your overall goal for the aquascape. We always recommend purchasing a little extra dry rock to ensure that you will have enough to complete the aquascape you are looking for, any extra rock can always be broken up and placed in your refugium, overflows, and sump for added filtration.


BRS makes every effort to securely pack the Rock.  However, the UPS automation is not always gentle on heavy products like this and they do not consider this product insurable. Because of this, there is some inherent risk with shipping rock like this across the country and it is impossible to replace or refund broken pieces. If this happens most pieces can be repaired with epoxy.

  • No Phosphates! By John on 4/20/2017

    So I am setting up a new tank and was going to buy live rock from the LFS but heard of some horror stories about getting nasty hitchhiking critters. I currently have no pests in my tank and didnt want to start now. So I ordered the BRS reef saver dry rock but some said even dry rock would have a lot of phosphates in them and they would have to be leached out before putting in the DT. I got a large trash can put the rock in and let it soak in fresh salt water with a power head and heater for 24 hours...then tested the P04 and my Hanna checker said 0.00. I didnt believe the meter so I soaked some food pellets in ro water for a few min then tested and got a reading of .64. So I tested the dry rock container again for the next several days and am still getting 0.00 on the Hanna checker! Dont know if I just got lucky with this batch of rock but really happy about No Phosphates! now I can just cycle the rock for a few weeks and it will be ready to go into the DT without the worry of leaching phosphates for the next 6 months or longer! Great Product.
  • Great rock, super easy to connect pieces together. By Jonathan on 4/5/2017

    Great rock to make aquaecapes! super easy and is cheaper then all the other rocks i have seen, will buy more in the future for sure!!
  • Great! By Tommy from Indy on 4/3/2017

    Great rock at a great price. Very porous rock. Easy to aqua scape with. Will purchase more in the future.
  • Awesome By Joseph on 4/1/2017

    Very well packaged, Very generous with amount, and they accommodated the sizes i wished for (was easy enough, over softball size, and under football size)

    Overall, another great experience. Thanks goes to all BRS employees!
  • Great By Tyler on 3/31/2017

    This is great rock. It looks good and fits together seamlessly. Can stack it easily
  • Great all around !! By Supermario on 3/30/2017

    Just great from the rock to the delivery!
  • Great Rock! By ryan on 3/16/2017

    I ordered the Reef Saver rock in hopes it would fulfill my needs after all reviews I read. Some said it broke apart easily and or the rock was too big as far as pieces for their tank. Let me tell you, I specified what size tank I had and what I planned to do i.e. 28 jbj need medium to smaller pieces. I ended up with 7 pieces with a few smaller rubble-esque pieces for the tank. The aquascape that is set up now is perfect....the only problem I have is, how do recreate this aquascape after it's emptied and washed. lol. I asked for pieces that provided a couple of "caves" and an "arch"...fully delivered! My guess is that people don't utilize the notes on "checkout" to specify what they want and or need. Handle that...and you get what you want. Thank you BRS! This order was awesome! BTW, the rock is way more porous than it even looks in the pictures. The rock was placed in a bag and surrounded by "peanuts" or "marshmallows" as my daughter called movement and no breakage. It takes some thought to arrange as there are multiple combinations. Just tell them what you want and they will oblige. Awesome job!
  • Awesome rock! By Blackhawkfan on 3/13/2017

    Very happy with the assortment of rock they sent.
  • BRS Included The Size Rocks I wanted By Garrett on 3/10/2017

    I've ordered this rock before. Easy to aquascape, great for bacteria, looks more consistent than pukani or fiji, however, last time I ordered 35lbs, i got 6 basketball sized rocks, and didn't know you could request a specific size. This time I ordered 35lbs and requested rocks the size of a football...They did an incredible job finding abt 15 nice looking rocks the size I requested! This is why I will always order my rock from BRS.
  • Rock is heavy By Jen on 3/9/2017

    Rock is heavy comparable to size, ordered 10# of this and 5# of pukani, ended up with about the same amount surface wise of both types of rock. This rock weights quite a bit more than the pukani.
  • Perfect sizes By Molli on 3/4/2017

    I ordered a meager 5lbs of rock, because I only needed a few pieces. I received one large and two small pieces which were perfect for my needs. The rock is light and beautiful and pretty clean.
  • Looks great By Christian on 3/1/2017

    The rock looks great, fits together smoothly and is easy to work with
